           //takes an input and covert it into char array.
          char st[] = sc.nextLine().toCharArray();    
         for (int i=0; i<st.length;i++)
         {//write  a string into the FOs.txt file
             fout.write(st[i]);
         }
         fin= new FileInputStream(file);
         int read;
         // read a string from the Fos.txt file.
         while((read=fin.read())!=-1)
         {
        System.out.print((char)read);
              }
      // releases FileOutputStream resources from the streams
         fout.close();    
        }
